Heidolph MR Series magnetic stirrers

Heidolph offers safe, convenient magnetic hot plate stirrers with a typical operational life span in excess of 10 years. The stirrers are suitable for smooth to intense mixing and heating of low-viscosity fluids or decomposing organic and inorganic substances.

The magnetic stirrers feature a KeraDisk hot plate, which allows for efficient heat transfer and fast heat-up times while being highly scratch and chemical resistant. Compared to lab mixers of 600 W, the MR Series of hot plates offer a heating capacity of 800 W, which reduces heat-up times by 35%.

An important safety feature to avoid unintentional heat-up is the separate illuminated on/off button for heating. Furthermore, an overheat sensor will switch off the hot plate if overheating occurs and the unit heater will automatically turn off in case of any other unforeseen accidents, such as a short circuit or motor failure.

The aluminium die-cast housing is said to make the hot plates virtually indestructible to thermal damage and also offers high corrosion resistance. The hermetically sealed housing will ensure that all electronic and mechanical components are protected from aggressive fumes typically present in fume hoods. Maintenance costs are therefore reduced, which makes the hot plate mixers a suitable choice, especially for inexperienced users.

The hot plate stirrers are compatible with Heidolph’s wide range of heat-on attachments, thus increasing efficiency for reactions of up to 45 samples.
